Printing blurring (vertical lines).
This may be caused by the scratches and damage of the gears of the platen motor.
Details of locating the damaged gear are described in the operation manual.
Location : Thermal head
Horizontal lines on the printed side of the paper.
This may be caused by tone unevenness of the head and wear of the head.
Location : Paper supply tray assembly, head link section
The print is badly out of position.
To locate the trouble area, print using the following method. First, print using a standard
size paper. The just before printing is completed, open the print cover.
The platen stops. Check the gap width between the black rubber of the platen and paper. If
the gap is consistent throughout from top and bottom, it means that the print is out of
position because the head is not attached at the proper position. Check the head link section
around the head attached.
If the gap is not consistent, check the paper supply tray.
